Why should anyone participate in your attempt to sidetrack the discussion,
cary? The answer to the question was posted days ago, the links to the
answer sheet were posted weeks ago, but even if you were to ever figure it

Tell us why you believe that GRE Quantitative scores and the 1995 TIMSS Math
scores correlate so closely with brain size, as well as with incomes, crime
rates, SAT Math scores, IAEP Math scores, GRE Analytical and Verbal scores,
the 1999 TIMSS scores, etc.

Or, conversely, tell us why you believe that American 12th grade girls
scored lower than if they'd just guessed on a THIRD of the questions at
